There was a small window of opportunity but nothing adds up to believe that happened. That was the strangest abductor in the world if he existed who had a weird habit of leaving doors half-open, raising noisy shutters and opening windows facing the world for no logical reason when the front door was hidden. A realistic crime scene would have Madeleine's bed in a mess and a wide open door where he left though and not a open window that was never used 8-)(--) The abductor is in and out as quick as possible and has a getaway vehicle ready to go. He is not RUDE Smithman running for his life.
So after conducting a forensic analysis of the timelines - in which all possible variations of what could have happened would be taken into consideration - SY - the experts - are still wrong?
The only thing that has changed since that statement was made is that now that Tannerman has almost certainly been identified, the opportunities for an abductor to take Madeleine are even greater than before.
There are several logical reasons why the window/shutters were opened - all of which have been posted before but all of which you apparently have chosen to ignore.
1. As a means of a sharp exit if disturbed, which via the window lessens the chances of 'confrontation' with anyone coming in via the patio doors.
2. As a means of checking that no-one was in the carpark - which could not be ascertained from the front door -without actually walking a couple of metres outside it and so risk being caught in the act of abducting Madeleine by someone in the carpark.
3. To take attention away from the fact that a key to the front door may have been used.
What is illogical about any of those reasons?
